It looks like you put the glider wing on and stretch a rubber band over the wing and around the little knobs.

Last year we had to have our previous cat put down. She came to us as a feral and we first saw her asleep in our garden. By using food I slowly got her to approach me until after about a week she came close enough for me to tickle her cheek. She got quite a shock and I am sure that no human had ever touched her before. I was then able to stroke her and pick her up. She immediately became 'my' cat and if she had her way she would spend all day asleep on my lap. When she was fifteen she got terminal health problems so we decided to have her put down before her quality of life degraded. I held her on my lap while the vet injected her, which was a trauma for all concerned, especially for the vet. The sight of a seventy year old man in floods of tears in quite heartbreaking.

My experience precisely!

We have one here in Melbourne, Australia. http://www.portphillip.vic.gov.au/Solar_System_-_Self_Guided_Walk.pdf

NASA has no incentive to keep costs down, nor any incentive to stretch out the use of their expensively-developed technologies. Whether the SLS costs $500 million per launch or $2 billion per launch, as a government agency, it knows that more funding will always be available if necessary. Can't agree with that statement.

Holding my breath usually works for me BUT you have to do it immediately the hiccup starts. Once the hiccups have set it in no longer seems to work.

News item this morning with an unfortunate choice of wording:- Queensland's first female motorcycle cops to hit the road

The glider altitude record is already at the maximum that a crew can survive without either a pressurised cabin or a full pressure suit, both a bit problematic in a glider. Gliders, with their long wings and low wing loading are quite happy at altitude. The previous record of 49,000 feet was set in a normal club-type glider with a 15 metre wingspan. I have been in a Piper warrior at 10,000 feet and it wallowed around very unhappily. I have been to 14,600 feet in a 15 metre wingspan glider and it felt no different to being at sea level. As an old glider pilot, the most interesting part of the article was the claim that mountain waves can penetrate the stratosphere. If this turns out to be true, then we have to rethink our definition of the stratosphere, which is a level of the atmosphere without vertical transport. i.e. only horizontal movements. I must say that the article just made me think of Boys playing with Toys!

That aircraft is a cri-cri and its real all right! https://en.wikipedia.org/wiki/Colomban_Cri-cri

'Starliner' is no different to 'astronaut', which translates from the Greek to 'star sailor'. Nobody expects either to actually go to the stars.

Of more interest to pre-spacecraft astronomers was a 'grazing occultation'. This is when a star just grazes the lunar horizon. Because the moon is not a perfect sphere and has no atmosphere to cause refraction the star will be hidden by mountains and become visible through valleys and so will seem to blink a few times. Without going into too much detail, if several observers in different positions time the exact moment and duration of the blinks it allows you to plot the altitudes and contours of the lunar horizon. This was useful in pre-spacecraft days but is now really only of interest to amateur astronomers.

I found this https://en.wikipedia.org/wiki/K%C3%A1rm%C3%A1n_line to be an informative read.

One advantage that was claimed for them was that you could make a big engine by mass-producing small ones and stacking several in a line. And you could 'throttle' it by turning a few off.

Here is a report written by another popular press journalist without the gee-wizz alien slant. http://www.abc.net.au/science/articles/2015/08/13/4292613.htm

I have a few movies that i could watch just about every day - the original Star Wars, Excalibur, Mad Max II, City of Lost Children, Little Shop of Horrors, Ghostbusters, and one or two others. I find it interesting that none of them could be considered 'good' movies. Movie buffs would sneer at them as being 'too commercial' and not 'artistic' enough. Bad movies? No idea where to start.

I clearly remember as a young boy in about 1953 or 1954 being earnestly told by an adult that space travel was impossible because there is no air up there for the rockets to push against. I wonder if later events caused him to change his mind?

I think that motorcycling tends to make the rider develop a kind of 'sixth sense', or more likely, an enhanced sense of 'situational awareness'. I remember once riding along a four-lane road and approaching a green traffic light. The light turned amber when I was so close that it was a toss-up whether to accelerate through or brake to a stop. I chose to brake and as I slowed down something told me to move over from the center of my lane to the white line between two lanes. As I came to a stop, one of those trucks that transport racehorses roared past my left elbow and through the red lights! Had I stayed in the middle of my lane I would almost certainly have been cleaned up. Shook me up for a while. I think that the OP heard the brakes and his brain said 'getohellouttahere!'. Just as well that there was a gap in front of him that let him do it.

I had never heard of Nibiru so I Googled it. Found the Wikipedia article but stopped reading at about the third line. Boy, are there some total whackos out there!

I vaguely remember reading somewhere that when Robert Stevenson was working on his early steam engine designs he patented the crankshaft! That stymied all other designers and is why some early steam engines used weird looking sun and planet gear wheels instead of crankshafts.

Agreed.

Picture doesn't show for me, which is a pity as it sounds like an interesting graph.

There are whole lot of reasons why a car will overheat but, as you say the water was rusty, the most obvious reason is that the inside of the engine block and the radiator core are partially blocked by rust. Flushing with clean water will not move this rust. You will need to get a radiator cleaning compound from a car accessory shop. follow the instructions and after you drain the water, which should be very rusty, repeat the process with more compound. If the water drains clean after the second go you should be all clean inside. If the car still overheats things will get a bit more difficult!

I may be way behind the times but I did not know about this. From Wikipedia:- Tombaugh died on January 17, 1997, when he was in Las Cruces, New Mexico, at the age of 90. A small portion of his ashes were placed aboard the New Horizons spacecraft. The container includes the inscription: "Interned herein are remains of American Clyde W. Tombaugh, discoverer of Pluto and the solar system's 'third zone'. Adelle and Muron's boy, Patricia's husband, Annette and Alden's father, astronomer, teacher, punster, and friend: Clyde W. Tombaugh (1906–1997)".

Everything in the ship would be quite normal to the crew. The ship would be traveling close to c RELATIVE TO some hypothetical observer. However, to the crew the ship appears to be stationary and the observer would appear to be travelling at close to c. Einstein's theory states that the speed of light is constant relative to the observer's frame of reference. For the observer, his frame of reference is wherever he happens to be. For the crew, their frame of reference is the ship they are in. Anyhow, that is how this only moderately well informed layman understands it. If I am wrong then I am sure that one of our more educated contributors will correct me.
